摘要
制备了 MPc- Fe3O4纳米复合粒子 (M=Co,Cu,Ni,Mn)与氯化石腊油组成了 EMR液 ,研究了其 EMR性能。结果表明 ,此类 EMR液在同时施加电场和磁场作用时表现出显著的协同效应。此 EMR液可长时间放置而不沉降 ,并且其 EMR性能放置后基本不变 。
The EMR fluids containing metallophthalocyanine(MPc)-Fe 3O 4 nanoparticles composite (M=Co, Cu, Ni, Mn) have been prepared. Their synergistic effect and stability have been studied. The results show that when electric and magnetic field are applied at the same time, the Δτ of these EMR fluids is much bigger than the sum of Δτ when H or E is applied separately. There is no sedimentation in these EMR fluids one year after they were made , and their EMR properties keep the same, which indicate that these EMR fluids have good long term stability.
